ALFRED H. HUMPHREY, OF NEW YORK, N. Y.

LAMP-GLOBE.

eaaseo.

To all whom it may concern:

Be it known that I, ALFRED H. HUMrnnnY, a citizen of the United States,residing at the city and State of New York, have invented certain newand useful Improvements in Lamp-Globes, of which the followmg is aspecification.

This invention relates to improvements in lamp globes.

My improved lamp globe is especially adapted and designed by me for useon my improved inverted lamps, such as is illus trated in Letters PatentNo. 841,323, dated Jan. 15, 1907.

The main object of this invention is to provide an improved lamp globewhich is adapted to be very readily and securely attached to itssupporting band, and when in position the globe is braced against theband when shaken as by a wind or otherwise vibrated.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearlyillustrated in the accompanying drawing, forming a part of thisspecification, in which: The figure is an ele vation of my improvedglobe, portions being broken away to better show its form, the globesupporting band being shown in section.

Referring to the drawing, the body 1 of the globe is preferablyspherical in form, as illustrated, and is provided with an attachingflange adapted to be inserted into the supporting band 2, and securedtherein by means of the screws 3. The attaching flange is provided witha cylindrical portion at its base adapted to fit the supporting band,and above its cylindrical portion, the flange is curved inwardly andthence outwardly to form an annular groove 5 with which the screws 3engage.

The upper edge of the attaching flange is turned inwardly, therebyforming a bead G, the bead being also adapted to fit the band 2. Thisflange is capable of withstanding very great strain, and is, therefore,not easily broken. And, further, the edge of the Specification ofLetters Patent.

Application filed January 18, 1909.

Patented Nov. 16, 1909. Serial No. 472,930.

flange being turned inwardly, is not likely to be engaged or hit on theedge of the supporting band, or other object, in adjusting which mightchip or break the same or crack the globe, and by thus shaping the globeis guided into position and the round edge permits it to slide to theprojection on the inside of the band such as the securing screw or thelike. A further advantage of this construction is that the globe is verysecurely held in its supporting band so that it is not likely to rattlefrom vibration of the lamp, or when exposed to the wind.

While I prefer to use the screws 3 as a securing means for the globe, assuch means are in common use, other .means of securing the attachingflange to the globe supporting band might be provided, but as suchmodifications and attaching means will be understood by those skilled inthe art to which this invention relates, I have not attempted toillustrate the same herein.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

l. The combination with a globe supporting band, of a globe having anattaching flange adapted to be inserted into said band, said flangebeing provided wit-h a cylindrical portion at its base adapted to fitsaid band, and being curved inwardly and thence outwardly and thenceinwardly to form an annular groove-like portion above said cylindricalportion and a bead-like. edge, said bead-like edge being adapted to fitsaid band; and screws arranged through said band to engage said grooveof said attaching flange.

2. The combination with a globe supporting band, of a globe having anattaching flange adapted to be inserted into said band, said flangebeing provided with a cylindrical portion at its base adapted to fitsaid band, and being curved inwardly and thence outwardly and thenceinwardly to form an annular groove-like portion above said cylindricalportion and a bead-like edge; and means for securing said attachingflange to said supporting band.

3. As a new article of manufacture, a globe having an attaching flangecomprising a cylindrical portion, an annular groove and a bead-likeedge, said cylindrical portion being at the base of said flange, saidflange being curved inwardly and thence out Wardly and thence inwardlyto form said my hand and seal in the presence of two groove and sandbead-llke edge. wltnesses.

c. As a new artlcle of n'lanufacture, a

globe having an attaching flange provided ALFRED HUMPHREY' with acylindrical port-ion the upper edge of Witnesses: snld flange belngturned lnwardly. J. P. CONROY,
